This loop starts at the bottom of Van Dusen Canyon Road (3N09) and climbs to Holcomb Valley Road (3N16). Turn left at the intersection and then right on Harvey Mine Road (3N43). Follow the route clockwise, staying right at any intersections. This part of the ride is a quite rough 4\u00d74 road that offers many technical challenges.
